Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, and in particular to a yarn pressing device for bread yarn. Background Technology

[0002] During the dyeing process of bread yarn, a pressing device is needed to compress the bread yarn, stringing it on a yarn rack and pressing it at a certain density to ensure the uniformity of the dyeing effect.

[0003] Most yarn pressing devices currently use a horizontal cylinder pressing method, and yarn pressing requires the cooperation of operators. However, because the cylinder valve is a pneumatic valve structure, the cylinder valve is prone to air leakage, which can cause injury to the operators. In addition, yarn pressing needs to be done in two stages, which is time-consuming and labor-intensive. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a yarn pressing device for bread yarn. By using a hydraulic cylinder instead of a pneumatic cylinder, it avoids injury to workers caused by valve leakage and can complete yarn threading and pressing operations in one go, thus effectively improving work efficiency and reducing the labor intensity of workers.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] This utility model provides a yarn pressing device for bread yarn, including a lifting hydraulic cylinder and a yarn pressing mechanism; the yarn pressing mechanism includes a pressure cover, a yarn guide rod, and a yarn loading assembly. The yarn loading assembly includes a yarn frame base and a yarn rod assembled on the yarn frame base. The yarn guide rod is detachably connected to the end of the yarn rod away from the yarn frame base. The pressure cover is detachably connected to the lifting end of the lifting hydraulic cylinder and is movably sleeved on the yarn guide rod. During yarn pressing, the lifting hydraulic cylinder drives the pressure cover to press down, so that the bread yarn is squeezed onto the yarn rod by the yarn guide rod.

[0007] Furthermore, the lifting hydraulic cylinder and the yarn loading assembly are respectively installed in two pits. A crossbeam is provided between the lifting end of the lifting hydraulic cylinder and the pressure cover. The crossbeam is assembled to the lifting end of the lifting hydraulic cylinder, and the pressure cover is detachably connected to the end of the crossbeam away from the lifting hydraulic cylinder.

[0008] Furthermore, the lifting end of the lifting hydraulic cylinder is equipped with a rotary drive assembly, and the crossbeam is mounted on the rotating end of the rotary drive assembly to drive the crossbeam and the pressure cap to rotate.

[0009] Furthermore, the rotary drive assembly drives the crossbeam and the pressure cap to rotate between -45 degrees and +45 degrees.

[0010] Furthermore, the end of the yarn guide rod opposite to the yarn rod is provided with an inclined guide surface, so as to facilitate the wrapping yarn being sleeved onto the yarn rod via the yarn guide rod.

[0011] Furthermore, after pressing the yarn, the pressure cap is detachably fixed to one end of the yarn rod away from the yarn frame base; the pressure cap, the yarn rod, and the yarn frame base cooperate to load the pressed yarn.

[0012] The technical solution provided by this utility model has the following beneficial effects:

[0013] The lifting hydraulic cylinder replaces the pneumatic cylinder used in the prior art, thus avoiding personal injury to operators due to valve leakage.

[0017] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. The components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0018] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0019] Reference Figures 1 to 3 This embodiment provides a yarn pressing device for bread yarn (hereinafter referred to as the yarn pressing device) to compress bread yarn before dyeing, thereby ensuring its subsequent dyeing effect.

[0020] like Figure 1As shown, the yarn pressing device of this embodiment includes a lifting hydraulic cylinder 1 and a yarn pressing mechanism 2 for pressing yarn. The yarn pressing mechanism 2 includes a pressure cover 21, a yarn guide rod 22, and a yarn loading assembly 23 for loading the bread yarn 6 during yarn pressing. The lifting hydraulic cylinder 1 is arranged vertically. Therefore, compared with the horizontally arranged cylinder in the prior art, this embodiment can further reduce the floor space.

[0021] The yarn loading assembly 23 includes a yarn frame base 231 and a yarn rod 232 mounted on the yarn frame base 231. The yarn guide rod 22 is detachably connected to the upper end of the yarn rod 232 away from the yarn frame base 231.

[0022] The pressure cap 21 is detachably connected to the lifting end of the lifting hydraulic cylinder 1 and is movably sleeved on the yarn guide rod 22 to ensure that when pressing the yarn, the pressure cap 21 is pressed down along the yarn guide rod 22 under the driving force of the lifting hydraulic cylinder 1 until the bread yarn 6 is squeezed onto the yarn rod 232.

[0023] In this embodiment, the lifting hydraulic cylinder 1 and the yarn loading assembly 23 are respectively installed in two pits 3, that is, the yarn frame base 231 and the mounting seat of the lifting hydraulic cylinder 1 are respectively placed at the bottom of the two pits 3, and the yarn rod 232 is vertically installed on the top of the yarn frame base 231.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, a crossbeam 4 is provided between the lifting end of the lifting hydraulic cylinder 1 and the pressure cover 21. The crossbeam 4 is assembled to the lifting end of the lifting hydraulic cylinder 1. The pressure cover 21 is detachably connected to the outer end of the crossbeam 4 away from the lifting hydraulic cylinder 1 through a clamping structure 211. In this way, the lifting hydraulic cylinder 1 can drive the pressure cover 21 to rise and fall through the crossbeam 4. Specifically, the outer end of the crossbeam 4 near the pressure cover 21 has a mounting slot 41 with a one-way opening. The pressure cover 21 has a clearance hole that cooperates with the movement of the yarn guide rod 22. The inner diameter of the mounting slot 41 and the clearance hole of the pressure cover 21 are both larger than the outer diameter of the yarn guide rod 22 to ensure that the yarn guide rod 22 can freely pass through the mounting slot 41 and the clearance hole of the pressure cover 21. The clamping structure 211 is detachably assembled to the pressure cover 21 and can be separately engaged with the mounting slot 41.

[0025] like Figure 1 As shown, before pressing the yarn, the bread yarn 6 is first placed on the yarn guide rod 22 to complete the yarn threading, and then the pressure cap 21 is placed on the upper end of the yarn guide rod 22.

[0026] During yarn pressing, the downward driving force of the lifting hydraulic cylinder 1 drives the pressure cover 21 to press down along the yarn guide rod 22 until the bread yarn 6 is squeezed into the yarn rod section by the pressure cover 21 to complete the yarn pressing.

[0027] like Figure 2As shown, after pressing the yarn, the guide rod 22 is first removed from the yarn rod 232, and then the pressure cover 21 is detachably fixed to the upper end of the yarn rod 232 away from the yarn frame base 231 by means of locking nuts, etc. Then, the pressure cover 21 and the crossbeam 4 are connected by the clamping structure 211. At this time, the pressure cover 21, the yarn rod 232 and the yarn frame base 231 work together to form a yarn loading frame 24 for loading the pressed yarn 6. Then, the entire yarn loading frame 24 containing the yarn 6 is lifted from the pit 3 by the lifting driving force of the lifting hydraulic cylinder 1. Then, the connection between the pressure cover 21 and the crossbeam 4 is released so that the yarn loading frame 24 can be removed.

[0028] In summary, by replacing the pneumatic cylinder used in the prior art with a lifting hydraulic cylinder 1, personal injury to workers due to valve leakage can be avoided.

[0029] Furthermore, the yarn guide rod 22, the pressure cap 21 and the yarn loading assembly 23 work together to complete the yarn threading and pressing operations in one go, which effectively improves work efficiency and reduces the labor intensity of operators. At the same time, the vertical layout ensures a small footprint.

[0030] Of course, in other embodiments, the pit 3 is optional, and the lifting hydraulic cylinder 1 and the yarn loading assembly 23 can also be placed on the ground or other mounting surfaces.

[0031] In another preferred embodiment, such as Figure 1 As shown, the lifting end of the lifting hydraulic cylinder 1 is equipped with a rotary drive assembly 5. If a conventional rotary shaft head structure is used, the crossbeam 4 is mounted on the rotating end of the rotary drive assembly 5 to drive the crossbeam 4 and the pressure plate 21 to rotate between -45 degrees and +45 degrees. This facilitates moving the pressure plate 21 closer to or further away from the yarn guide rod 22, and removing the yarn loading frame 24 from the pit 3. Furthermore, through the combined action of the lifting hydraulic cylinder 1 and the rotary drive assembly 5, the pressure plate 21, the yarn guide rod 22, and the yarn loading assembly 23 can not only be raised and lowered, but also rotate within a certain angle range. Of course, the rotary drive assembly 5 is optional.

[0032] Further preferred, such as Figure 1 As shown, the upper end of the yarn guide rod 22, which is away from the yarn rod 232, is provided with an inclined guide surface 221 to facilitate the wrapping yarn 6 to be sleeved onto the yarn rod 232 via the yarn guide rod 22.

[0033] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
